Should also consider the http://openprovenance.org/model/opmo, as described in the OPMV announcement by Jun Zhao:
This first release of OPMV achieved the maximum compatibility with
another OPM implementation, the Open Provenance Model Ontology (OPMO,
http://openprovenance.org/model/opmo), which implements OPM using much
more complex OWL constructs. How the OPM terms can be mapped to other
existing provenance-related vocabularies has been analysed under a W3C
Provenance Incubator Group task force .
These may be more relevant to documenting graphs of data via the application ontology than to the data in any graph
In this week's small team meeting we said we'll treat all the issues as Blockers unless specifically decided otherwise for a particular issue. I'm doing a bulk set of all priorities to Blocker and we can lower particular issues on an individual basis.
